I use the same 10,000-row file on two machines, a Linux box with mediocre specs, and a powerful MacBook Pro M1 Max with 32GB RAM. On the Mac, scrolling is much, much slower than on the Linux laptop.
A test case is in this related bug,
Version: 18.104.22.168 (X86_64) / LibreOffice Community
Build ID: 53bb9681a964705cf672590721dbc85eb4d0c3a2
CPU threads: 10; OS: Mac OS X 13.3.1; UI render: default; VCL: osx
Locale: en-US (en_US.UTF-8); UI: en-US
It's not really fast at zoom-level 65%. It's faster at zoom 160%. I have no linux comparison..
but there is lag between releasing fn + arrow up and the scrolling on screen.

Scrolling is also painfully slow if running LibreOffice as root, see https://bugs.documentfoundation.org/show_bug.cgi?id=153985#c15
